integrity constraint
<database> A constraint (rule) that must remain true for a database to
preserve integrity. Integrity constraints are specified at database creation
time and enforced by the database management system.
Examples from a genealogical database would be that every individual must be
their parent's child or that they can have no more than two natural parents.
